Lucille Potter (d. 1943) was a nurse that hooked up with Mutt Daniels and his squad in Illinois. Despite Daniels' discomfort, Lucille insisted on acting as their medic. She helped save Kevin Donlan's life after a Lizard shell blew off his left foot. She was a lesbian, and resisted Daniels' advances.

Potter was killed when a shell fragment hit her between the eyes. Daniels mourned her death.
